摘要
利用激光热应力效应建立了一种检测软质涂层结合强度的装置, 分析了激光热应力作用下残余应力表征涂层界面结合强度的原理与方法, 可对软质涂层进行检测。结果表明, 激光热应力作用下涂层残余应力发生变化, 可用节点残余应力作为界面结合状况的检测信号来表征界面结合强度; 激光热应力检测软质涂层界面结合强度方法可替代传统拉伸法, 实现实时在线检测涂层界面结合强度。
Abstract
A device measuring bonding strength of soft coating based on laser thermal effect was established, and the mechanism and method for characterizing interfacial bonding strength of coating by residual stress under laser action were analyzed, which is suited for measuring bonding strength of soft coating. The experimental results show that residual stresses of the coating are changed under laser thermal stress, and residual stress in the node can be used to measure the interfacial bonding strength of the coating. Tradition pulling method can be replaced by the method of coating interfacial bonding strength with laser thermal stress, and the real time measurement of coating bonding strength was realized in the real-time way.
